What is the expected phenotype of F1 progeny from a cross between two homozygous recessive mutants disrupted in different genese
LenaWriter [7]

Answer:

The correct answer would be - wildtype.

Explanation:

Let assume there are four genes which are :

A-B-C-D

In mutant first, the genotype would be:---a-b-C-D

In the mutant second, the genotype would be:--A-B-c-d

If both of these genotypes are crossed with each other, the recessive genes a, b of mutant first is dominated and masked the expression by the dominant genes present in the mutant second.

Similarly, the recessive genes of the mutant second are dominated and masked expression by the dominant genes of mutant first.  This is possible only due to different genes are present in mutants.

Thus, the correct answer is - The correct answer would be - wildtype.

Which of the following are compounds? (Choose all that apply.)
STatiana [176]

Answer:

Water, organic biological molecules, sodium chloride, glucose.

Explanation:

A compound is anything composed of two or more separate elements.

  • O2 and H2 are a singular elements, and a chain of carbon atoms is multiple of the same element, so these are not considered compounds.
  • Sodium chloride is sodium and chlorine, and water is oxygen and hydrogen. Glucose is a compound of sugar, and organic biological (or biomolecules) are made up of carbon and hydrogen, so these are all considered compounds

I hope this helps! Happy learning, friend :)
